APPENDIX F.2 : EXAMPLE OF STANDARD IMPACT ASSESSMENT VOLUME 2 (ATTACHMENT B - A3 ):

RESULTS FOR RIVER ARIES

STANDARD IMPACT ASSESSMENT for reservoirs owned by Xenon plc on

Rivers Anduin, Aries and Kappa

Preface 1. This example Impact assessment, although based on a real cascade, has been edited in respect of key features

of the cascade and downstream valley to preserve the anonymity of the dam, including names.
